Prevalence of Salmonella enterica and Listeria monocytogenes contamination in foods of animal origin in Italy.
Serotyping showed that approximately 50% of the isolates belonged to the serotypes most commonly isolated from humans in Italy, thus confirming that most cases of human salmonellosis have a foodborne origin. Expand
Two cases of type E infant botulism caused by neurotoxigenic Clostridium butyricum in Italy.
The first two confirmed cases of type E infant botulism occurred in two 16-week-old girls in Rome, Italy, and the apparent causative organism in each case resembles Clostridium butyricum but produces a neurotoxin that is indistinguishable from type EBotulinal toxin by its effects on mice and by its neutralization with type E botulinal antitoxin.

Distribution of serotypes and pulsotypes of Listeria monocytogenes from human, food and environmental isolates (Italy 2002-2005).
When associations between subtypes and isolates from specific foods selected as being most frequently involved in cases of listeriosis were tested some of these associations were highly significant but not exclusive, indicating that there was no close correlation between specific sub types and specific food products.

Incidence of Listeria monocytogenes in food and environmental samples in Italy between 1990 and 1999: Serotype distribution in food, environmental and clinical samples
The strains isolated were biochemically and serologically characterised and showed a prevalence of a few serotypes which were the same as those found in clinical samples collected during outbreaks and from sporadic cases of listeriosis reported in Italy in the period considered. Expand
Listeria monocytogenes serotypes in human infections (Italy, 2000-2010).
In Italy the surveillance laboratory network, as well as the foodborne disease network (ENTER-NET), has revealed in the last 11 years an increase trend of listeriosis cases reported likewise with results of Notificable National Infectious Disease surveillance System, probably due to a real increase of listersiosis, even if there is a greater sensitivity of the network in some regions.

Listeriosis associated with gorgonzola (Italian blue-veined cheese).
The results stress the importance of developing a code of hygienic practice for preventing, limiting, and where possible, eliminating this pathogen in processed foods and of educating at-risk persons on foods likely to be contaminated. Expand
Clostridium botulinum spores and toxin in mascarpone cheese and other milk products.
A total of 1,017 mascarpone cheese samples, collected at retail, were analyzed for Clostridium botulinum spores and toxin, aerobic mesophilic spore counts, as well as pH, a(w) (water activity), andExpand
European validation of a real-time PCR-based method for detection of Listeria monocytogenes in soft cheese.
The results of this international trial demonstrate that the evaluated real-time PCR-based method represents an excellent alterative to the ISO standard since it shows a higher performance as well as reduce the extent of the analytical process, and can be easily implemented routinely by the competent authorities and food industry laboratories. Expand
Results of a 12-month long enhanced surveillance of listeriosis in Italy.
Of the 77 cases of listeriosis, 41 Listeria monocytogenes isolates were characterised by serotype and pulsotype; more than 95% of the strains belonged to serotypes 1/2a, 4b and1/2b; molecular analysis revealed 23 different AscI pulsotypes. Expand
European validation of Real-Time PCR method for detection of Salmonella spp. in pork meat.
This study presents an international (at European level) ISO 16140-based validation study of a non-proprietary Real-Time PCR-based method that can generate final results the day following sample analysis that represents an excellent alternative to the ISO standard. Expand
